“…El conocimiento de los patrones de distribución de las especies de murciélagos presentes en Ecuador ha cambiado sustancialmente en las últimas décadas. Obras como las revisiones de Albuja (1982Albuja ( , 1999, Tirira (1999Tirira ( , 2007 y Gardner (2008), han contribuido de manera sustancial a un mejor entendimiento de la distribución de muchas especies; aportes que se han visto fortalecidos con numerosas revisiones y estudios que han aparecido en los últimos años (entre ellos Reid et al 2000;Albuja y Mena-V. 2004;Lee et al 2006a, b;Lee et al 2008;Tirira 2008;Lee et al 2010;Carrera et al 2010). Sin embargo, todos los esfuerzos previos por explicar la distribución de las especies de murciélagos en el Ecuador se han basado únicamente en registros de colecciones e intervalos altitudinales; sin considerarse patrones ecológicos y ecosistémicos, formaciones vegetales o características bioclimáticas, que ayuden a un mejor entendimiento de la distribución potencial de los quirópteros en el país.…”

The knowledge of the distribution of bat species in Ecuador has changed significantly in recent years, from new records to taxonomic revisions that have shaped distribution maps to a broader biogeographic understanding. A review of the richness patterns and potential distribution of bats in Ecuador is presented, based on the analysis of records published or stored in scientific collections using Ecological Niche Modeling (ENM) tools. Although maps resulting from ENM are limited both because of the lack of equilibrium and limitations on the representativeness of samples, they constitute a better depiction of distribution than minimal convex polygons or altitudinal ranges. According to the Ecuadorian Red List, 19 species of bats are currently threatened, mainly because of habitat conversion as a consequence of recent colonization, so a better understanding of distribution and spatial richness will result in better proposals for research-priority and conservation-priority areas. Methodology: The analysis was based on 21,455 records, corresponding to 162 species. This information was reviewed and validated using Geographic Information Systems. A maximum entropy algorithm implemented in Maxent was used to evaluate and generate potential distribution models of the species. Those species with insufficient data to generate a model or for which the evaluation was unsatisfactory were eliminated from the analysis. The remaining species models were used to create a composite map representing the richness of bat species for Ecuador, which in turn was used to assess the conservation status of bat diversity in the country. Results: Following review and validation of the data, 10,916 records were used to determine the potential distribution of 81 species of bats, based on ENM. A map of potential bat species richness was obtained for the country with the overlap of the models, representing areas that due to climatic conditions, allow a higher or lower species richness of bats living in sympatry. We determined that the central and northeastern foothills of the Andes are the most suitable areas enclosing the highest richness of bats in Ecuador. Researchpriority and conservation-priority areas were identified. Discussion and conclusions: Information on protected areas of Ecuador was overlaid on top of the potential richness map, showing that only 5.6% of the area with the greatest potential bat richness is protected. Accordingly, we determine the existing information gaps and identify priority areas for research and conservation of bats in Ecuador. Three research-priority areas were defined: (1) the Southeastern tropics, between Pastaza and Morona Santiago provinces; (2) the Northern Andes towards the cordillera's western slopes; and (3) areas of the Western dry tropical forests, between the provinces of Guayas and Manabí.

“…1, whereas T. cinereus sensu stricto is sister to a lineage that includes T. shallqukucha , T. lojapiuranus , and T. pagaibambensis (of which the last two are sister species). All other relationships within this clade have only weak to moderate support, but it is noteworthy that the Ecuadorean taxon identified as T. cinereus by Lee et al (2018)—denoted as T. “sp. 2” in these results—is not closely associated with the species complex that includes T. cinereus sensu stricto.…”

“…More recently, Pacheco (2015) provided an updated account of Thomasomys cinereus , describing the species afresh, comparing it with other congeners known at that time, and reporting marginal localities from the Peruvian departments of Cajamarca (west of the Río Marañón), La Libertad, Lambayeque, and Piura. Subsequently, T. cinereus has also been reported from the province of Loja in southern Ecuador (Lee et al, 2018; Moreno-Cárdenas and Novillo-Gonzalez, 2020). Although Pacheco (2015) considered T. cinereus monotypic, he suggested that it might be a species complex.…”

“…Phylogenetic analyses of cytochrome b sequence data have provided molecular support for some of Pacheco's (2003, 2015) species groups (Salazar-Bravo and Yates, 2007; Lee et al, 2015, 2018; Brito et al, 2019, 2021). In particular, Lee et al (2018) and Brito et al (2019) both recovered a monophyletic Cinereus Group, but T. cinereus was represented in their analyses only by Ecuadorian specimens, the identification of which has yet to be convincingly established. Genetic data obtained from topotypical specimens of T. cinereus and specimens from other Peruvian populations currently referred to T. cinereus have yet to be analyzed.…”

Quimsacocha National Recreation Area is located on the western slope of the Andes in Azuay Province, southern Ecuador. All sampling locations were in the high paramo and high Andean forests (3,572 to 3,865 m). The habitats include paramo, bogs, riparian, patches of elfin forests, and secondary cloud forest. We set Sherman, pitfall, and camera traps (3,600 trap nights), and mist nets to collect 117 specimens. Eight species were collected, including Caenolestes caniventer Anthony 1921; Didelphis pernigra J.A. Allen, 1900; Cryptotis montivagus (Anthony, 1921); Akodon mollis Thomas, 1894; Microryzomys altissimus (Osgood, 1933), Phyllotis haggardi Thomas, 1908; Sigmodon inopinatus Anthony, 1924; and Sylvilagus andinus (Thomas, 1897). Two additional species Coendou rufescens (Gray, 1865) and Odocoileus virginianus (Zimmermann, 1780) were documented photographically. This is the first survey that saved voucher specimens for mammals of Quimsacocha.
